I remember in my first year at the University I and many of my classmates had no clue on how to calculate CGPA.
The calculation of CGPA at the University sounded like complex mathematics work. In fact, some persons had to pay for the calculation of their results.
Well, the calculation of CGPA is not a complex mathematics problem. It is easy and you can do it yourself.
In this post, I will be showing you the easy way that you can use to calculate the GPA for your first and second semesters.
You will learn how to calculate GPA from CGPA. Also, you will know how to calculate CGPA in Nigerian Universities like the University of Ibadan, UNN, AAU, UNILAG, NOUN, OAU, UNIPORT, UNILORIN, etc. and other tertiary institutions in Nigeria.
First-year and other students will find this post helpful. But first, let me explain the meaning of GPA and CGPA in Nigerian Universities.
Let me know in the comment box if you need clarifications. I will get back to you as soon as possible.

First Semester GPA Calculation
| PointCourse Code | Unit | Grade | Point | Unit x Point | Total |
|---|---|---|---|---|---|
| ACC 101 | 2 | D | 2 | 2 x 2 | 4 |
| COS 101 | 3 | A | 5 | 3 x 5 | 15 |
| PHI 101 | 2 | B | 4 | 2 x 4 | 8 |
| MAN 101 | 2 | E | 1 | 2 x 1 | 2 |
| MTH 111 | 3 | C | 3 | 3 x 3 | 9 |
| MAN 141 | 3 | A | 5 | 3 x 5 | 15 |

| GSP 105 | 2 | C | 3 | 2 x 3 | 6 |
| Total | 19 | 25 | 63 |
You will divide the total point by the total number of credit unit loads for the first semester.
Total Point = 63
Total Unit = 19
GPA = 63/19 = 3.32
Second Semester Course Outline
| Course Code | Course Title | Unit |
|---|---|---|
| ACC 102 | Elements of Accounting II | 2 |
| PSY 101 | Introduction to Psychology | 2 |
| BF 101 | Introduction to Finance | 2 |
| MTH 112 | General Mathematics II | 2 |
| MAN 142 | Elements of Business Economics II | 3 |
| GSP 102 | The Use of English II | 2 |

| Total | 15 |
Second Semester Result
The table below shows the second-semester result we would for the calculation.
| Course Code | Course Title | Score | Grade |
|---|---|---|---|
| ACC 102 | Elements of Accounting II | 65 | B |
| PSY 101 | Introduction to Psychology | 56 | C |
| BF 101 | Introduction to Finance | 44 | E |
| MTH 112 | General Mathematics II | 59 | C |
| MAN 142 | Elements of Business Economics II | 78 | A |
| GSP 102 | The Use of English II | 49 | D |
| GSP 106 | Natural Science II | 81 | A |
First Semester GPA Calculation
| Course Code | Unit | Grade | Point | Unit x Point | Total |
|---|---|---|---|---|---|
| ACC 102 | 2 | B | 4 | 2 x 4 | 8 |
| PSY 101 | 2 | C | 3 | 2 x 3 | 6 |
| BF 101 | 2 | E | 1 | 2 x 1 | 2 |
| MTH 112 | 2 | C | 3 | 2 x 3 | 6 |
| MAN 142 | 3 | A | 5 | 3 x 5 | 15 |

| GSP 106 | 2 | A | 5 | 2 x 5 | 10 |
| Total | 15 | 23 | 51 |
You will divide the total point by the total number of credit unit loads for the second semester.
Total Point = 51
Total Unit = 15
GPA = 51/15 = 3.4
CGPA
CGPA stands for cumulative grade point average. It is an addition to your first and second semester GPA.
Now the final step is to add the GPA of both semesters and divide it into two (2) to get your CGPA.
| Semester | GPA |
|---|---|
| First semester | 3.32 |
| Second semester | 3.4 |
| Total |
CGPA = First semester GPA + Second semester GPA / 2
CGPA = 3.32 + 3.4 / 2 = 3.36
Final Year CGPA
The final year CGPA is an addition of your CGPA from the first year to your final year divided by the number of years of study.
Below is the CGPA of a student from the first year till the final year.
| Level | CGPA |
|---|---|
| 100 | 3.36 |
| 200 | 4.5 |
| 300 | 3.9 |
| 499 | 4.7 |
| Total | 16.46 |
Final CGPA = Total CGPA / 4
Fianl CGPA = 16.46/4 = 4.1
